. To all whom. it may concern:

Be itknown that I, JosErH H. GLAUBER, acitizen of -theUnited States, residing at Cleveland,in theicounty of Cuyahoga and State of s Ohio,

have invented-certain new and useful Improvements-in Stop and Waste Cocks; and I do declare that the following is a full, clear, and exact description ofthe-invention, which will enable others skille'din theart to which 19 it. appertainsto ma keand use the same.

My invention relates to improvements in stop and waste cocks; and the invention 0011- Ind-a 1- Anyone. nu

astop-and wastecock in which there are a main valve t'o'closethe flow of the water & through the cock and a waste-valve for con-- trollingthe waste-outlet, all substantially as out in the claims.

Referring to the accompanying drawings,

shown and described and particularly pointed Figurelis a central sectional elevation of a "stop and waste'cockembodying my invention and showing the'main'valve closed and the'waste-valve open. Fig. 2"is a cross-section of the cockath'ightangles toiFig. 1

maybe either on'tlie op'posite side'of the cock in Fi'g." 1 or inflth'e cuteawayside at'the front. Figlis a'mo'difica'tion'of the inven 5 "D is athreaded val'veacontrollmg stein or spindle "having a handle E to turn the valve to and from itsseat, and F is a threaded plug in which the'val've-spindle is engaged.

Now in order that this mechanism may bef ntillzedfor stop "and waste purposes I'- have formed thebody' or casing of the cock with a waste well or chamber G, and this; chamber is'lo'catefd at a point directlyjopposite" the seatQ of themain valved 'whether'the cock be vertical or'h'oriaontal; and is packed and closed on its-outside against leakage.

".lwo waste-wa ter ducts or passages are connected witlithis well'or chamber, the inlet duct or passage '3, Fig. 1, which commm 5o nicates with the waste side, of tussock to' draw or waste the water out of 'th'epipe'when the'main valve is closed, and the outlet-duct projection 8 andintersecting-the outlet-passage-from the waste-valve chamber,"but which passage tion with a ditferent form-of "main valve, as-

or passage 4, Fig. 2, leading from the top or inher side of said well or chamber out through the discharge-nipple 5. 7

It will be noticed that the chamber G is shown here directly below valve 13. This is made possible by arranging said valve above theseat and diaphragm 0, so as to open upward. Then beneath said diaphragm O, be low the water space thereunder, is. a diaphragm 6, forming the top or inner wall of the Waste=chamben From 'this .wall there extendsa tube 7 upward to valve-B, and downward through said tube is a stem or 130-1363,?" on the waste-valve, as hereinafter described. A waste-valve K occupies the chamber G and closes upward against the outlet-passage 4, while the inletpassage 3 is always behind said valve.

The stem ,8 isj'designed to so closely occupy the neck 7 that it Will close it against .water passage or pressure from above.

.The projection or point 8 on valve B bears *on the waste-valve K when valve B is closed, and valve K is supported 9 resting on the bottom of chamber G and pressing the valve 'toits seat. A spring of such strength aswill simply hold said valve K to its seat will besufficient, because I do not in fact rely on the spring to hold the valve 'to its seat, but on the pressure of the water, and the heavier this pressure the closer the valve is held. It will be noticed that the illlet-passage 3 discharges into chamber G be- "neath valve K, even when said-valve is open,

and the stem or projection 8 is of such 'length that said valve will be opened relatively about as shown when the main valve is closed. Ilene-e as soon as the stem 8 is withdrawn by opening the main valve the waste-valve is pressed to its seat not only by the spring 9, but by the back pressure of the 'ater from below. i I may of course use a 'spring'of sufficient strength to hold the valve K firmly to its seat; but my construction and arrangement of parts have the advantage of being able to utilize the water-pressure alone for this purpose or as a reinforcement of the spring.

111 Fig; 331. show a modification of theinvention, in which I employ a straightway spects the invention is the same, substantially 0 0 I by aspiral spring valve L in the casing-M; but in all other reare employed to efiect the waste.

. Among the advantages of my invention over waste-cocks heretofore in use I may mention the following:

, First. The old style of cocks, when used in a horizontal position, would not allow the waste water which was in the pipes to run oil on account of the waste-hole being up so high above the seat that it was above the level of the pipe to be drained. In my cook the waste is belowthe level of the pipe, and it will waste whether set, horizontally or vertically.

' Second, All the ordinary-cocks waste continually from the time of opening the valve until the stem is turned entirely up, requiring it to be screwed around several times before closing'can occur. Therefore they cannot be used partly open or partly closed, and theslightest turn of the stem niakes them leak out of the vaste. 1 i

My waste is not disturbed until the main valve is practically closed, and .the' waste closes instantly when the main valve is opened. Furthermore, mycock wastes from beneath the seat and at the same time has the pressure on the lower side and not against anyof the'workingparts when closed. Again,

my waste-valve can be removed forwrepairswith'ontdisconnectlng or disturbing the main valve-a very great advantage.

Theterms top and bottom, beneath 'and f. above, or the like when applied to the main valve in its relation to, the wastechamber or to said chamber or its valve in relation tothe main valve are understood to apply whether the cock be set in a'horizontal ora vertical positionythese terms serving especially to simplify'description.

By closing the-main valve from above its" seat the said valve islbrought onto the ex, haust side of the seat, and this enables me to place the waste-chamber and mechanism directly beneath said seat and beneath thewater-pressure and yet' not have the waterpressure directly open to the waste mechanism. Vhen the main valve is open, however,

the pressure comes through and into' the waste-chamber, as already described, v

It will be observed that bythe foregoing construction there are two diaphragms C and 6 .in parallel planesandihetwee'n whichihere. is a constant presence of the pressure fluid.

This brings the Waste-chamber directly beneath the pressure fluid and'is rendered possible by the tubular neck 7, extending up from diaphragm 6 and affording away to communicate mechanically from main valve B to the said exhaust-chamber through the water-pressure over said chamber.

\Vhat I claim is v 1. In stop and waste cocks,-the body of the cock constructed with two parallel diaphragms having a space between them constantly open to water-pressure, and a tubular projection from one of said diaphragms I into 2. The body of the cock having two dia phrag'ms-and a waste-chamber beneath the same, one of said diaphragms having a passagejfor the water and the othera' projection i nto'the space between said diaphragms and.

open through its center into the said waste-' chamber, substantially as described.

The body of the cock provided with two diaphragmsmne of said diaphragms having a seat for the main valve and a waste-chambercoveredv by the other diaphragm in which is a central passage opening-into, saidwa'stechamber, in combination with the wastevalve, the main valve and a close-fitting projection extending through said central passage a-nd engaging said waste-valve, substaniially as described. 1 I

4/ The body of'the cock having two diaphragms with an open water-pressure space between them, and a waste-chamber beneath the lower of said diaphragms having its waste at the top, in combination withfa main valve, seated on the upper diaphragm and an ex haust-valve seated on the lower diaphragm to close said outlet, and a projection from the main valve engaging the waste-valve, substantially as described.

5. The body of the cock having the mainvalve diaphragm therein, andawaste-chsmber having-a diaphragm closing the top thereof; the main valve and the waste-valve arranged to seat toward each other on said diaphragms respectively, and a waste-outlet be-, tween said valves controlled by the wastevalve, and a projection from the main valve engaging the waste-valve to open the same,

substantially as-described.

6. A stop and waste cock having one diahra m dividin said cock'into'waterressure and exhaust sides and provided with a valve-seat and a valve opening to the exhaust side from said seat, a waste-valve .chamber opposite said seat and a separate diaphragm over the-same separating said chamber from 1 the water-pressure side of the cook, a valve in said'chamber and means to open said valve as described.

Q7, Thebody of-ihe cock provided with a.

main-valve diaphragm across its center and a valve seated on the exhaust side of said diaphragm, a waste-chamber beneath said main valve and a diaphragm closing it from the water-pressure over the same, a waste-valve in said waste-chamber and means extending to the main-valve stem to open the wastevalve, substantially as described. VVit-ness my hand to the foregoing specification this 4th day of November, 1897.
